Outstanding Weathering and Anti-Aging Performance: Featuring a hydrogenated saturated molecular structure devoid of unsaturated double bonds, it provides exceptional resistance against ultraviolet rays, ozone, and high-temperature thermal aging. It resists yellowing, cracking, and performance degradation during long-term outdoor exposure, making it well-suited for long-service-life operating conditions.
Balanced Melt Flow and Processing Stability: With an MFR of 15-23 g/10min, it offers a moderate fluidity range, matching diverse manufacturing processes such as injection molding, extrusion, solvent dissolution, and hot-melt modification. It boasts a wide processing window and high mass-production stability, minimizing molding defects.
Excellent Compatibility and Oil-Extension Performance: Featuring a stable 30/70 styrene-to-rubber ratio, it exhibits outstanding compatibility with general-purpose plastics such as mineral oil, PP, and PE. It supports high-ratio oil extension to adjust softness and tactile feel without bleeding or blooming, delivering exceptionally high formulation adjustability.
High Purity for High-End Compliance Scenarios: Maintained with extremely low levels of volatiles, total extractables, and ash content, paired with a compliant antioxidant additive system, the material remains pure and stable without harmful precipitation. It fulfills baseline material requirements for consumer goods, medical appliances, and food-contact auxiliary components.
Superior Flexibility and Dimensional Stability: Designed with a soft Shore A60 hardness alongside stable tensile strength and elongation at break properties, finished goods offer excellent recovery resilience and fracture resistance under stress. It exhibits low dimensional shrinkage rates across varying thermal environments, supporting soft elastomer goods manufacturing.
Eco-Friendly and Recyclable, Aligning with ESG Standards: Classified as a thermoplastic elastomer that is halogen-free and non-toxic, it can be recycled and reprocessed, aligning with global plastics environmental compliance and sustainability standards.
Backed by stable weather resistance, high compatibility, and excellent processability, KRATON G1726 M SEBS is extensively deployed across multi-industry high-end elastic products and modification formulations:
Adhesives and Sealants: Serving as a core base material for hot-melt pressure-sensitive adhesives, construction sealants, and industrial bonding agents, it delivers high initial tack, sustained bonding stability, and durable weather resistance for outdoor sealing and fixed bonding applications.
Polymer Modification: Utilized for toughening general-purpose plastics such as PP, PE, and PS, it enhances matrix toughness, impact resistance, and low-temperature performance while mitigating brittleness defects in plastic molding.

Q1: Is pre-drying mandatory for KRATON G1726 M SEBS prior to processing?
A: No. The SEBS raw material exhibits extremely low water absorption under sealed storage conditions, making pre-drying unnecessary for routine injection molding, extrusion, or modification processes. If packaging is damaged or exposed to condensation, drying at 80-90 °C for 2-3 hours is recommended to remove surface moisture and prevent molding defects such as bubbles, silver streaks, or uneven bonding.
Q2: What are the core advantages of this grade compared to ordinary domestic SEBS alternatives?
A: As a premium imported SEBS from Kraton, G1726 M features a precisely controlled viscosity range, minimal volatile and ash content, and a batch-to-batch stability that significantly outperforms general domestic grades. Furthermore, its higher degree of hydrogenation yields more prominent UV resistance, thermal aging resistance, and anti-yellowing performance, alongside superior oil-extension compatibility and zero blooming issues, fitting high-end, weather-resistant, and high-purity industrial formulation contexts.
Q3: Does KRATON G1726 M comply with RoHS and REACH environmental regulations?
A: Yes. This imported SEBS grade utilizes an eco-friendly, halogen-free formulation, ensuring the virgin material conforms to European Union RoHS and REACH environmental compliance standards without restricted hazardous substance additions. For overseas exports, client factory audits, and compliance testing, original manufacturer TDS, MSDS, and COA documentation can be provided to support global market access requirements.
Q4: What modification formulations suit this grade, and what precautions apply to oil extension?
A: G1726 M is well-suited for mineral oil extension, plastic toughening modification, and adhesive formulation modification, offering a high oil-extension ratio and exceptional compatibility. Processing requires controlled compounding temperatures and screw speeds to ensure thorough integration between the oil and resin, avoiding localized compounding inconsistencies that could cause tactile deviations or insufficient elasticity in finished goods. Small-scale trial runs are recommended prior to mass production to confirm formulation parameters.
